Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically to a pressure reducer assembly for a fire extinguishing device for kitchen equipment. Background Technology

[0002] As people's living standards improve, the types and quantities of kitchen equipment are constantly increasing, and the risk of kitchen fires is also increasing accordingly. As an important fire safety device, the performance and reliability of kitchen equipment fire extinguishing devices are of paramount importance. Fire extinguishers are one of the common fire prevention facilities, and nitrogen is one of the filling materials in fire extinguishers. However, existing fire extinguishers do not have a device to reduce the pressure of nitrogen when releasing it, which leads to the exhaust pipe of the fire extinguisher rupturing due to the inability to withstand the pressure brought by nitrogen, posing certain hidden dangers during use. Therefore, pressure reducing device components are needed.

[0003] The prior art patent document CN216222703U provides a nitrogen pressure regulator for a kitchen equipment fire extinguishing device. By opening the manual valve, the nitrogen in the tank rushes into the installation groove through the gas outlet channel and pushes the pressure reducing plate to rise. Under the action of the first pressure reducing spring and the second pressure reducing spring, the pressure reducing plate buffers and reduces the nitrogen pressure in the tank, thereby enabling the device to achieve the purpose of reducing nitrogen pressure and improving the stability of the device.

[0004] While the aforementioned existing technology can effectively reduce pressure, it suffers from poor sealing due to the lack of a sealing ring between the mounting frame and the threaded cylinder. Furthermore, damaged parts within the pressure-reducing box are difficult to disassemble and replace, and prolonged use may cause wear at the connection points due to component movement, leading to gas leakage. Therefore, we need a pressure-reducing component for kitchen equipment fire extinguishing devices. Utility Model Content

[0005] The purpose of this invention is to provide a pressure regulator assembly for a kitchen equipment fire extinguishing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pressure reducing device assembly for a kitchen equipment fire extinguishing device, comprising a tank, a pressure reducing box fixedly connected to the top of the tank, an insulation sleeve provided on the outer wall of the pressure reducing box, a pressure reducing component provided on the inner wall of the pressure reducing box, and a protective component provided on the outer wall of the tank.

[0007] The pressure-reducing component includes a lid, and the inner wall of the lid has a sealing groove. A sealing ring is provided on the inner wall of the sealing groove. A mounting base is fixedly connected to the inner wall of the lid, and a spring is fixedly connected to the inner wall of the mounting base. A sliding frame is fixedly connected to one end of the spring, and a pressure-reducing plate is fixedly connected to one end of the sliding frame.

[0008] The protective assembly includes a base, a limit block welded to the outer wall of the tank, a threaded groove on the inner wall of the base, and a threaded rod threadedly connected to the inner wall of the threaded groove. One end of the threaded rod is fixedly connected to a long rod, and one end of the long rod is fixedly connected to a fixed handle.

[0009] Preferably, the inner wall of the pressure relief box is provided with an exhaust pipe, and one end of the exhaust pipe is provided with an exhaust valve.

[0010] Preferably, the inner wall shape and size of the sealing groove match the outer wall shape and size of the sealing ring, and the inner wall of the sealing groove fits into the outer wall of the sealing ring.

[0011] Preferably, there are two mounting bases, and the two mounting bases are symmetrically arranged with the vertical line of the lid as the axis of symmetry.

[0012] Preferably, the base forms a threaded structure through a threaded groove and a threaded rod, with one end of the threaded rod extending into the threaded groove for connection.

[0013] Preferably, there are multiple long rods, and the multiple long rods are arranged in a ring at equal intervals.

[0014] Preferably, one end of the long rod passes through the limiting block.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model includes a lid, a sealing groove, a sealing ring, a mounting base, a spring, a sliding frame, and a pressure-reducing plate. By installing a sealing ring inside the lid of the pressure-reducing box, the sealing performance between the lid and the pressure-reducing box can be effectively improved, preventing gas leakage. When gas from the tank enters the pressure-reducing box, the gas pressure acts on the pressure-reducing plate, pushing the pressure-reducing plate upward, thereby compressing the spring inside the mounting base. The spring generates a reaction force during the compression process, resisting the gas pressure and thus reducing pressure. The structure is simple, the pressure-reducing effect is good, and it can effectively protect the exhaust pipe of the fire extinguishing device, preventing it from rupturing due to excessive pressure, thereby improving the safety and stability of the fire extinguishing device.

[0017] Secondly, this utility model is equipped with a base, a limiting block, a threaded groove, a threaded rod, a long rod, and a fixed handle. By setting multiple equally spaced annular long rods, the tank can be well protected. By rotating the long rod through the fixed handle, the long rod drives the threaded rod to rotate out of the threaded groove, which allows the long rod to be replaced. The operation is simple and convenient to use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, a pressure reducing device assembly for a kitchen equipment fire extinguishing system includes a tank 1, a pressure reducing box 2 fixedly connected to the top of the tank 1, an insulation sleeve 3 provided on the outer wall of the pressure reducing box 2, a pressure reducing component 4 provided on the inner wall of the pressure reducing box 2, and a protective component 5 provided on the outer wall of the tank 1. The pressure reducing component 4 includes a cover 401, and a sealing groove 402 is formed on the inner wall of the cover 401. A sealing ring 403 is provided on the inner wall of the sealing groove 402. A mounting base 404 is fixedly connected to the inner wall of the cover 401. A spring 405 is fixedly connected to the inner wall of the tank 1. A sliding frame 406 is fixedly connected to one end of the spring 405, and a pressure reducing plate 407 is fixedly connected to one end of the sliding frame 406. The protective component 5 includes a base 501. A limit block 502 is welded to the outer wall of the tank 1. A threaded groove 503 is opened on the inner wall of the base 501. A threaded rod 504 is threadedly connected to the inner wall of the threaded groove 503. A long rod 505 is fixedly connected to one end of the threaded rod 504, and a fixed handle 506 is fixedly connected to one end of the long rod 505.

[0025] Through the above technical solution, by installing a sealing ring 403 inside the cover 401 of the pressure reducing box 2, the sealing between the cover 401 and the pressure reducing box 2 can be effectively improved, preventing gas leakage. When the gas in the tank 1 enters the pressure reducing box 2, the gas pressure acts on the pressure reducing plate 407, pushing the pressure reducing plate 407 to move upward, thereby compressing the spring 405 in the mounting base 404. The spring 405 generates a reaction force during the compression process, resisting the gas pressure and playing a role in pressure reduction. The structure is simple, the pressure reduction effect is good, and it can effectively protect the exhaust pipe 6 of the fire extinguishing device, avoiding rupture due to excessive pressure, thus improving the safety and stability of the fire extinguishing device. By setting multiple equidistant annularly arranged long rods 505, the tank 1 can be well protected. By rotating the long rods 505 through the fixed handle 506, the long rods 505 drive the threaded rods 504 to turn out from the threaded grooves 503, allowing the long rods 505 to be replaced. The operation is simple and convenient to use.

[0026] Specifically, the inner wall of the pressure reducing box 2 is provided with an exhaust pipe 6, and one end of the exhaust pipe 6 is provided with an exhaust valve 7.

[0027] The above technical solution controls the gas discharge by setting an exhaust valve 7; the cover 401 can be fixed to the pressure reducing box 2 by bolts, and the bottom of the tank 1 is welded with a base 501.

[0028] Specifically, the inner wall shape and size of the sealing groove 402 match the outer wall shape and size of the sealing ring 403, and the inner wall of the sealing groove 402 fits into the outer wall of the sealing ring 403.

[0029] The above technical solution enhances the connection between the sealing groove 402 and the sealing ring 403, and strengthens the sealing between the pressure reducing box 2 and the box cover 401 by providing the sealing ring 403.

[0030] Specifically, there are two mounting bases 404, and the two mounting bases 404 are symmetrically arranged with the vertical line of the cover 401 as the axis of symmetry.

[0031] By using the above technical solution and by setting two mounting bases 404, the stability of movement is enhanced when the pressure reducing plate 407 moves.

[0032] Specifically, the base 501 forms a threaded structure with the threaded rod 504 through the threaded groove 503, and one end of the threaded rod 504 extends into the threaded groove 503 for connection.

[0033] The above technical solution enhances the connection between the base 501, the threaded groove 503, and the threaded rod 504. The threads in the threaded groove 503 match the threads on the threaded rod 504, making it easier for the threaded rod 504 to be threaded into the threaded groove 503.

[0034] Specifically, there are multiple long rods 505, and these multiple long rods 505 are arranged in a ring at equal intervals.

[0035] The above technical solution, by setting multiple long rods 505 to surround the tank 1 in a ring, can effectively protect the tank 1 and reduce the risk of damage to the tank 1 due to external forces.

[0036] Specifically, one end of the long rod 505 passes through the limiting block 502.

[0037] Through the above technical solution, the limiting block 502 is provided with multiple circular grooves, the inner wall of the circular grooves is in contact with the outer wall of the long rod 505, so that one end of the long rod 505 can pass through the circular grooves on the limiting block 502.

[0038] In use, the operator first manually opens the exhaust valve 7, allowing nitrogen gas from tank 1 to enter the pressure reducing box 2, pushing the pressure reducing plate 407 upward. The movement of the pressure reducing plate 407 causes the sliding frame 406 to move, making the sliding frame 406 more stable within the mounting base 404. This movement compresses the spring 405 within the mounting base 404. The spring 405 generates a reaction force during compression, resisting gas pressure and thus reducing pressure. This effectively protects the exhaust pipe 6 of the fire extinguishing device from rupture due to excessive pressure. By setting multiple equidistant, ring-shaped long rods 505, it is possible to... During installation of the protective tank 1, one end of the long rod 505 is passed through the limiting block 502, and the threaded rod 504 on the long rod 505 contacts the threaded groove 503. By rotating the fixing handle 506, the threaded rod 504 is rotated into the threaded groove 503 and fixed. During disassembly, the long rod 505 is rotated by the fixing handle 506, and the long rod 505 drives the threaded rod 504 to rotate out of the threaded groove 503, so that the long rod 505 can be replaced. The operation is simple and easy to use. This completes all the work. The contents not described in detail in this manual are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
